A breakthrough from the construction of traditional heat meter is made. A heat meter with transformable rotary-wings is developed by making some modification pm a hot-water meter. The rotary-wings of the heat meter are made from metal sheet with two layers typed 5J11, and the precision of the heat meter is tested in hot-water. When the temperature of hot-water is between 40 degree and 80 degree, the error is less than ±5%. Compared with other heat meters, this heat meter with trans formable rotary-wings is much simpler and cheaper.
